Haha!! It took me a while to understand your question, To my left is a bottle of Stolichnaya Vodka and a bottle of Orange Juice.

(1.) I could drink the vodka to dull the pain of being eaten.
(2.) Once I've drank the vodka I could use it to bluggin the Zombies bastards brains in, well until it shattered.
(3.) Shout the zombies a few rounds of Russia's finest Vodka which will then leave them even more Fucked up! allowing me to make a run for
rendezvous point.
In all honesty I would probably just sit back and drink the vodka and pass out waking up the next day with a killer head ache and thinking" Shit where was that rendezvous point again oh well i'll just sleep the hang over off and deal with that later..ZZzzzzz!!!
